Inhibition of cellular protein synthesis by double-stranded RNA: inactivation of an initiation factor.

abstract：:A 2.9-kilobase Acc I fragment of the DNA of the pneumococcal bacteriophage Cp-1, containing the cpl gene, hybridizes with the lytA gene encoding the pneumococcal amidase. The nucleotide sequence of the cpl gene of Cp-1, encoding a muramidase (CPL), has been determined. The 3' regions of the cpl and lytA coding sequenc...
